In her new biography as a solo artist, Nadine Coyle talks about the time she spent being a Girls Aloud and recording with Xenomania:

"We developed a machine-like mentality. I don't regret a second of it. It taught me amazing discipline. I learnt everything I needed to learn about myself as a singer and songwriter from Brian [Higgins]. We made some amazing records with him. And I got to do that alongside four great girls".

Nadine also talks about how her dream was singing songs where "every line means the world to you" with the full back-up of a live-band . She says that the closest she got to that dream with Girls Aloud was when the five girls wore the sparkling gold gowns in "The Promise" video. She even adds that "The Promise" is among the top five songs Girls Aloud ever made.

She also talks about her vocal register in Girls Aloud: "If you listen to all the Girls Aloud records, they're in a really low register. It was because I'd just come off tour and we had to record with my throat tired from three months singing at full energy on the road. I didn't want to have the same constrictions this time."

There is also an interesting paragraph in her biography that explains in a very succint and superficial way how Girls Aloud's albums were made:

«If in modern music industry terms two years seems like a lengthy gestation period for an album, consider for a moment how long Girls Aloud were given to put their five records together. Nadine Coyle has certainly earned her dues. At the end of every one of their ever-increasing tours, Nadine would be sequestered off to the house of GA producers Xenomania in deepest, darkest Kent. She’d work with producer Brian Higgins for two weeks, three maximum, putting vocal licks for songs together, run off on holiday for a week and then return. A week for mastering and bingo! There’s your album. Six weeks, maximum.»

Exactly. Those albums were tailor-made for Girls Aloud. The girls are the writers' and producers' muses. Some songs took years to complete. They didn't fall from the sky. They didn't magically appear within those six weeks.

Xenomania is a songwriting and production house based in Kent, England. It was founded by songwriter and producer Brian Higgins.

Since 1996, Xenomania have written, produced and remixed tracks for a string of successful artists including Girls Aloud, Pet Shop Boys, Sugababes, Dannii and Kylie Minogue, Saint Etienne, Cher, Gabriella Cilmi and many others.
